Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterGelco Fireplace Services in White Plains: What to Know First
We provide independent Gelco fireplace services in White Plains, with most repairs completed in a single visit and pricing agreed before we start. A typical Gelco gas fireplace service runs $180-$340, while firebox or damper repairs on Gelco wood-burning units generally fall between $450-$890 depending on parts and access. We’re not here to sell you a full replacement when a targeted repair will do.
This page is for White Plains homeowners who already own a Gelco fireplace, insert, or gas log set and need honest diagnostics, OEM or quality aftermarket parts, and a crew that knows the difference between a Gelco GVF36 vent-free issue and a GD80 direct-vent problem. Call (914) 603-1360. A live person answers, 24 hours a day.

How Gelco Products Fail - and How We Fix Them
- GVF36 vent-free gas fireplace - pilot won’t stay lit after windy days. This is a White Plains-specific pattern we see in homes near the Gedney Farm neighborhood and along the Bronx River Parkway, where older chimney flues create downdrafts that overwhelm the GVF36’s oxygen depletion sensor. The ODS isn’t broken; it’s doing its job too well. We clean the pilot orifice, verify flue draw with a manometer, and if the chimney can’t be made to vent properly, we’ll tell you straight that a vented unit is the safer path.
- GD80 direct-vent gas insert - discolored glass and sooting on the lower edge. Gelco’s GD80 series uses a sealed combustion chamber that depends on precise air intake balance. After 8-12 years, the intake termination hood on White Plains homes often clogs with cottonwood seed in spring or fine masonry dust from aging chimneys. We disassemble the termination, check the intake-to-exhaust ratio with a digital gauge, and replace the gasket set. Aftermarket gaskets work fine here; we use Copperfield’s high-temp kit, which outlasts the OEM paper gasket in our field notes.
- Gelco wood-burning fireplace - cracked refractory panels in the firebox. The factory panels in pre-2005 Gelco units were a thinner cast refractory that doesn’t tolerate thermal shock well. White Plains homeowners who burn green or unseasoned hardwood (we see a lot of oak and maple stored too close to the house) get panel cracks by year seven or eight. We measure the panels in place, order HeatShield-compatible replacements or factory panels depending on availability, and reset them with proper expansion gaps. A rushed panel job without those gaps cracks again in two seasons.
- Gelco fireplace damper - won’t open fully or hangs crooked. Gelco’s cast-iron throat dampers from the 1990s and early 2000s used a pinned hinge that seizes when creosote glazes in the throat. In White Plains, where we get freeze-thaw cycles that accelerate masonry spalling, we’ve found the pin hole itself wallows out before the damper plate fails. We can bush the hinge and re-pin, or if the frame is too far gone, we retrofit a Lock-Top or Lyemance damper with a Gelco-compatible frame. We photograph the throat before we quote so you see exactly why replacement beats repair.
- Gelco gas log set - delayed ignition or “popping” on startup. The G18 and G24 vented log sets use a single-tube burner that carbonizes at the ports after roughly 500 hours of burn time. White Plains basements and converted garages with Gelco installs often have dustier air, which accelerates this. We pull the logs, ultrasonic-clean the burner, check gas pressure at the valve (should read 3.5″ WC for natural gas, never assume), and replace the ember bed if it’s compacted. The fix takes about 90 minutes; we’ve done enough of them that we carry the common burner orifices on the truck.
Our Gelco Fireplace Services Process
- 1
You call, a live person answers. We ask the model number if you have it, the symptoms, and whether the unit is gas or wood. No phone tree.
- 2
We arrive in a marked truck, uniformed, and on time. Russell Haines or one of our background-checked techs inspects the unit, not a trainee sent to upsell.
- 3
Level-2 camera inspection and digital photos. For wood-burning Gelco units, we run a camera up the flue. For gas units, we check combustion analysis, gas pressure, and venting. You see the images; we give you a plain-English verdict.
- 4
Parts decision: OEM or quality aftermarket. If Gelco factory parts are available and cost-competitive, we use them. If lead time is six weeks or the OEM price is unreasonable, we source equivalent from our regular suppliers - DuraFlex for liners, HeatShield for refractory, Copperfield for gaskets and hardware. We tell you which we’re using and why.
- 5
The repair, tested before we leave. Gas units get a full burn cycle test with CO check. Wood units get a smoke-puff draft test. We clean our work area.
- 6
Written invoice, 90-Day Done Right Promise attached. The number matches the estimate. If something’s not right, we come back. No paperwork, no arguing.
What Gelco Fireplace Services Costs in White Plains

| Gelco gas log set burner replacement | $340 - $580 | Single-tube vs. dual-tube burner, ember bed and grate condition |
These are real White Plains numbers, not national averages pulled from a database. Your actual estimate depends on what we find, which is why we don’t quote blind over the phone.

Why White Plains Homeowners Call Hearthstone Chimney Co. for Gelco Work
We’ve been servicing homes in White Plains for over 42 years, including the older colonials near Gedney Farm where the masonry tells you exactly how long a chimney has been ignored. Russell Haines learned this trade at Los Angeles Trade-Technical College and has spent well over two decades in it since; he keeps a worn field notebook going back fifteen years because, as he’ll tell you, a chimney will repeat itself if you let it.
Our techs know Gelco’s product line well enough to spot a GVF36 ODS issue in ten minutes, not two hours of billing. We work with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - no builder-grade substitutes. The 90-Day Done Right Promise is in writing, not a verbal shrug. And when you call (914) 603-1360, a live person answers, every hour of every day.
If the chimney’s doing its job, you won’t think about it. That’s exactly where we want to leave things.
FAQs
No. As an independent Gelco service provider, we perform repairs that do not void manufacturer warranties, provided we use OEM or equivalent-spec parts and follow proper installation procedures. We document parts and methods so you have that record if needed. For warranty claims still within Gelco’s coverage period, we can advise whether the factory or our service is the faster path. Call (914) 603-1360 and we’ll sort it out.
Common Gelco parts - gaskets, pilot assemblies, refractory panels for recent models - we can often source within 3-5 business days through our regular suppliers. Older or discontinued series may take 2-3 weeks for OEM, which is when we discuss quality aftermarket alternatives from HeatShield or Copperfield that we trust in the field. We never leave you guessing on timeline; we confirm parts availability before we schedule the repair.
Replace when the firebox is structurally compromised, the flue liner is failing and can’t be relined cost-effectively, or repair costs exceed 60% of a new unit installed. Repair when the issue is isolated to the gas valve, damper, refractory panels, or burner - which covers most of what we see in White Plains homes. We’ll show you the camera footage and give you both numbers so you decide. Call (914) 603-1360 for an exact quote; estimates are free.
Once annually, before the heating season. Even a clean-burning Gelco direct-vent unit accumulates dust on the burner, the pilot orifice narrows, and the blower motor (if equipped) needs inspection. In White Plains, where we see extended shoulder seasons that lead to intermittent use, annual service prevents the “worked fine last year” surprise that usually happens on the first cold night. Call (914) 603-1360 to schedule; our $89 Seasonal Tune-Up covers the essentials.
Creosote accumulates in the flue, increasing chimney fire risk. The damper corrodes or seizes. Cracked refractory panels let heat reach the framing. Carbon monoxide can backdraft if the flue is partially blocked. These are real hazards, not scare tactics - we’ve documented each one in White Plains homes. That said, we’ll also tell you when a minor crack can be monitored rather than immediately repaired. Call (914) 603-1360 for an inspection and an honest assessment of what can wait.
